It's decided, the crossover rule will be added.
Ok, so I saw that people were arguing in order to add crossovers to the board, and I decided that it was a good idea to add a new rule about it, so if we agreed on adding one, I shall edit rule 3 and 4 and add that crossovers are allowed, but 3 or less, no more than 3 crossover, so:
Thanks for voting!
